Man Finds 3.92-Carat White Diamond

A Wisconsin man digging at an Arkansas diamond park with his fiancee Tuesday found a 3.92-carat white stone, but the rock will go into his collection because his betrothed already has a ring and a setting.

Eric Blake, 32, of Appleton, Wis., spotted the stone along a trail at the Crater of Diamonds State Park when he set down a 70-pound bucket of mud that he was carrying to a wash basin. "I put the bucket down to switch hands. I looked down and there it was," Blake said.

Blake found a 1.49-carat stone Monday. The larger one is big enough to fashion into jewelry but Blake hadn't decided whether he will have it placed into a setting. "I only found it an hour ago," he said.

More than 700 diamonds have been found at the park this year. The Crater of Diamonds park is the world's only diamond-producing site open to the public and visitors can keep the stones they dig up.
